To all whom it may concern:

Be it known that I, FRANK K. ARNOLD, a subject of the King of Great Britain, of Nashua, in the county of Hillsboro and State of New Hampshire, have invented certain new and useful Improvements in Paper-Feeders, of which the following is a specification.

i This invention relates to devices for feeding flat articles, such as pieces of paper or pasteboard, in disk or other form, the object of the invention being to provide a simple and rapidly operating feeder capable of supplying preferably a plurality of the articles, side by side, to mechanism which will act upon, or treat the articles while in transit.

Afurther object of the invention is to provide a feeder of this nature which will operate continuously and at a very high speed, without liability of lapping each other as they pass to and between the treating rolls.

To these ends the invention consists in the improvements which Ishall now proceed to describe and claim.

Of the accompanying drawings,Figure 1 is a side elevation of so much of the machine as is necessary to illustrate my invention. Fig. 2 is a plan view, partly broken out, or in section.

Similar reference characters indicate the same or similar parts in all of the figures.

Mounted in suitable bearings in the frame 10, are upper and lower rolls 11 and 12.

Said rolls may be so formedand constructed as to print, emboss, stencil, coat or otherwise treat the flat articles which are passed or supplied to them by my improved mechanism. As my invention relates to the feeding mechanism, rather than to the part operated upon, or treatment of the articles fed, it is unnecessary to illustrate any construction for printing, embossing, or other wise treating the articles.

My improved feeder comprises abed or table 13, suitably supported by the frame of the machine, and having a horizontal slot or slots 14, above which are mounted a series of vertical magazines 15 for the articles.

1n the drawings, the magazinesflfi are indicated as circular in cross-section, to accommodate circular disks. 1 do not limit myself, however, to this particular form of the magazines'in cross-section.

Specification of Letters rattle.

the articles overmagazine in Patented July 21, in it.

A slide 16 mounted in suitable Ways provided upon or by the frame of the machine, has a series offorwardly projecting'pushers 17, which comprise thin plates, preferably having concave front or pushing edges, as shown in Fig. 2. These pushers or plates 17 are adapted to reciprocate through or in I the slot 14, each of the said plates and the slot having a thickness substantially the same as that of the articles which are placed in the magazines, and which descend by gravity, so that the bottom-most one in each magazine will rest on the table 13, when the pusher is retracted, in position to be carried through the slot 14, when the pusher is advanced, as presently described, to be introduced between the nip of the' rolls 11, 12.

Mounted in uprights of the slide 16 is a,

rod 18. The intermediate portion of said rod might, however, be omitted. The ends of the rod, or the pins which would bethe result of omitting the middle portion of the rod, are'connected to the ends of two pitmen .19 mounted upon eccentrics 20 carried by a shaft 21, said shaft being driven by any suitable means, such as gearing 22 connecting the shaft 21 with the shaft of the lower roll 12.

In operation the magazines 15 are loaded with a pile of articles, such as flat paper disks, so that the disks will descend by gravity to present the bottom one in each front of a pusher 17. The rotation of the shaft 21 causes the eccentrics and the pitmen to reciprocate the slide so that the pushers will eject the articles that are in front of them, the throw of the eccen: tries and pitmen being such that the advancing movement of the pushers will carry the blanks or articles in the magazines descend to present another series of them in front of the pushers, in position to be fed to the rolls by the next advancing movement of thepushers. The rolls 11, 12, constantly revolving in the direction of the arrows (Fig. 1), advance the articles which have been introduced thereto out of the way of the next series of blanks or articles that are fed by the pushers. As the articles leave the rolls 11,12, they are picked off from the lower roll by a guide plate 23 which delivers them to a conveyer, which may consist of a continuous string or cord 24, passing over long pulleys 25, 26, the latter being carried by a shaft 27 having a driving pulley 28, said shaft 27 being mounted in bearings carried by standards 29.

Power may be communicated from the pulley :25 to the shaft of the lower roll 12, by a suitable gearing, such as a sprocket and chain gearing, indicated at 30.

The slot M constitutes an outlet from the magazine or magazines, leading to a point in proximity to the nip of the rolls 11, 12, the portion of said slot which is at the lower end of the magazines being so proportioned as to permit the'passage of but one article at a time from each magazine, the pusher for each magazine serving to positively transfer just one article at a time from each magazine. It will therefore be understood that the mechanism is capable of operating with great rapidity, without 'any liability of the articles overlapping, either side by side from the different magazines, or as they are supplied from each individualmagazine. The number of magazines, side by side, may be greater or lesser than illustrated in Fig. 2, the slide, of course, being of such length,

- and carrying a requisite number ofipushers,

to cause the pushers to simultaneously feed a row of the articles to the treating rolls. By recessing the acting ends or edges of the pushers, the-articles are fed to the rolls without any possibility of their crowding each" other. This recessing of the operative portions of the pushers enables a perfectly smooth table to be employed, without any guides for directing the thin flat articles to the nip of the rolls. It also results in the machine being made more compact than one where guides are necessary for the articles, and enables the machine to be operated rapidly without liability of the articles becoming jammed during transfer from the magazines to the treating rolls.

I claim 1. A machine of the character described, comprising a pair of treating rolls, a series of magazines having outlets in proximity to the nip of said rolls, said outlets being proportioned to permit the passage of but one article at a time from each magazine, a series of pushers having recessed operative ends movable in said outlets for positively transferring articles to the nip of the rolls, and means for reciprocating the pushers a distance to transfer the articles the entire distance from the outlets of the magazines to the rolls.

2. A machine of the character described, comprising a pair of treating rolls, a row of tubular magazines'mounted closely adjacent said rolls and having slotted outlets leading to the nip of said rolls, a slide having a series of pushers movable through the said outlets, sald pushers having recessed operative ends to engage and guide articles from the bottoms of the magazines, and means for reciprocating the slide and pushers a distance. to transfer the articles the entire distance from the magazines to the rolls.

3. A machineof the character described, comprising a pair of treating rolls, a row of tubular magazines mounted closely adjacent said rolls and having slotted outlets leading to the nip of said rolls, a slide having a se ries of pushers movable through the said outlets, said pushers having recessed operative ends to en age and guide articles from the bottoms of the magazines, a shaft having eccentrics, pitmen operatively connected with said eccentrics, and connections between said pitmen and the pushers whereby the latter are reciprocated to feed articles from the bottoms of the magazinesto the nip of said rolls, the eccentrics being proportioned to cause one stroke of the slide and pushers to carry articles from the magazines to the nip of the rolls.

In testimony whereof I have aflixed my signature, in presence of two witnesses.
